See three new pages in the Earth Art Gallery. I learned recently that those newfangled walls along highways—those ones that look like fake bedrock, because they are?—are the work of actual trained sculptors. As I've said in connection with Earth art, "nothing that supports artists is really a failure." An example of roadside shotcrete sculpture is just one of the three new pics. This globe, in San Francisco's Yerba Buena Gardens, is another.
